Action on data

On the data of the table defined, you can perform the following
operation:

Insert: Adds new entries to the table.

Update: Updates entries in the table.

Delete: Deletes the entries which
correspond to the entry flow.

Schema and Edit
Schema

A schema is a row description. It defines the number of fields
(columns) to be processed and passed on to the next component. When you create a Spark
Job, avoid the reserved word line when naming the
fields.

Click Edit
schema to make changes to the schema. If the current schema is of the Repository type, three options are available:

• View schema: choose this
  option to view the schema only.

• Change to built-in property:
  choose this option to change the schema to Built-in for local changes.

• Update repository connection:
  choose this option to change the schema stored in the repository and decide whether
  to propagate the changes to all the Jobs upon completion. If you just want to
  propagate the changes to the current Job, you can select No upon completion and choose this schema metadata
  again in the Repository Content
  window.

Built-in: The schema is created and
stored locally for this component only. Related topic: see
Talend Studio User Guide.

Repository: The schema already exists
and is stored in the Repository, hence can be reused. Related topic: see
Talend Studio User Guide.

Where clauses for (for UPDATE and DELETE
only)

Enter a clause to filter the data to be updated or deleted
during the update or delete operations.

Use different table name

Select this check box to define a different output table name,
between double quotation marks, in the Table
name field which appears.

Mapping

Specify the metadata mapping file
for the database to be used. The metadata mapping file is used for the data
type conversion between database and Java. For more information about the
metadata mapping, see the related documentation for Type mapping.

tStatCatcher Statistics

Select this check box to gather the Job processing metadata at a Job
level as well as at each component level.

Global Variables

NB_LINE: the number of rows read by an input component or
transferred to an output component. This is an After variable and it returns an
integer.

NB_LINE_INSERTED: the number of rows inserted. This is an
After variable and it returns an integer.

ERROR_MESSAGE: the error message generated by the
component when an error occurs. This is an After variable and it returns a string. This
variable functions only if the Die on error check box is
cleared, if the component has this check box.

A Flow variable functions during the execution of a component while an After variable
functions after the execution of the component.

To fill up a field or expression with a variable, press Ctrl +
Space to access the variable list and choose the variable to use from it.

For further information about variables, see

User Guide.
